Laser beam machining is a non-traditional subtractive manufacturing process, a form ofmachining, in which a laser is directed towards the work piece for machining. This process usesthermal energy to remove material from metallic or non-metallic surfaces. The laser is focusedonto the surface to be worked and the thermal energy of the laser is transferred to the surface,heating and melting or vaporizing the material. Laser beam machining is best suited for brittlematerials with low conductivity, but can be used on most materials. The role of the technicalequipment in laser milling is to perform a controllable action of the laser radiation on thematerial to be treated. The laser is the main unit of the equipment and it is characteristicsdetermine to great extent the qualitative and quantitative parameters of the technologicaltreatments.In this work, I had to study the laser milling process parameter selection for processplanning operations from start to finish. It was important to have an understanding about lasermilling and laser processing parameters for different materials. As a result from the laser milling,the surface finish will have different surface properties such as, surface hardness, surfaceroughness, friction and tribology etc.. During the process, I gained knowledge about thehistorical and conceptual framework of laser milling, the different parameters of a laser millingand how the laser milling parameters influence the surface properties of the machined parts.
